RAILWAY FROG. Y

Application viledtugust 23, 1322. Serial` No. 583,828.

Frogs, of which the following is a specication. This invention relates to an improved railway frog and seeks, as one of its principal objects,.to provide a frog which will form a safe and rigid connection between the rail ends coacting with thefrog.

The invention has as a Jfurther object tov provide a frog wherein jolting of rolling` `stock passing` thereover will be minimized. t

And the invention has as a st-ill further object to provide a frog which may be readily installed.

' Otherand incidental objects will appear hereinafter. l

In the drawings:

Figure 1 is a plan viewrshowing my improved frog in conjunction with a railway switch, v Figure 2 is a perspective view of the frog,

Figure 3 is a bottom plan view ofthe device, and

4 Figure 4 is a transverse sectional view on the line 4 4 of Figure 1. p

In carrying the invention into effect, I employ a block10 flared or widened from a point medially thereof toward its ends. The blockis, as shown inFigure 2 ofthe drawings, provided with a flat upper faceand at one side edge is, formed with. an. upstanding tread rib 11 'and an angulaily .disposed guard rib 12 while at its opposite side edge the block is provided with a similar tread rib13 and angularly disposed guard rib 14, the ribs'conforming to the outline of the side edges of the block. Upstanding from the upper face of the block between the diverging ends of the ribs 11 and 13 is a medially disposed double-ended frog point 15 substantially diamond shaped in contour and upstanding from the upper face of the block between the diverging ends of the guard ribs 12 and 14 is a medially disposed triangular shaped frog point 16. Intersecting flangeways 17 and 18 are thus defined between the frog points, the tread ribs 11 and 13 and guard ribs 12 and 14, and at the ends of these tlangeways the upper face of the block is cupped to provide entrance depressions 19. Formed in the adjacent end of the block to aline with the tread ribs 11 and 13 are slots 2O definingl longitudinallydirected tongues 21 which form the outer side wallsV of said slots.` These slots are provided with `flat vertical inner end walls 22, it being noted in-this connection vthat the adjacent endsof` the tread ribs 11 and 13 provide continuai tions of said walls, and formed in the lower side `of the block at said slotsgare seats 23 to accommodate the base anges of railstting in said slots. y v i .Extendingfrom the base end of theffrog point 16 is an upstanding tail rib V24 and projecting lfrom the adjacent end ofthe block is a triangular shaped extension 2,5

lying medially between the diverging ends of the guard ribs 12 and 14. The upper face of the extension as well as the upper face of the tail rib 24 ,lie flushv with the frog point 16` and formedin the blockat oney side of said extension is a slot 26 at the outerlend., of which the block is provided with a tongue 27 .lying in spaced parallel relation tothe adJacent face of the extension. The sloty 26, like theslots 20, is provided with alat ver tical inner end wall and', aswill be observed..

the tail rib 24 as well as the upper side of the extension arecut. away to deiine a rail tread seat 28 terminating at-*the base end of the frogipoint', the baseend of the frog point forming a continuation of the inner4 end wall of said slot. Formed in the lowerI side of said extension as well as in the lower side of the block is, as, shown inFigure 3, a

seat 29 to accommodate the baselange of a rail fitting in the slot 26. `Formed in the the tail rib 24`is a slot 30 defining a tongue 31 forming the outer side wall of said slot. Theextension is cut away at its upper side Lextension inalinement with the ybase end of to provide a seatv32 for theftread ofva rail ,t fitting in'said slot and is likewise cut away at its lower side tofprovide a 'seat' 33 for the base flange of the rail. The slot 30, like the slot 26 isprovided with a fiat vertical inner end wall and the base end of the tail rib 24 l provides a continuation of said wall.

InFigure 1 of the drawings, I have shown my improved frog in connection with va railway switch. Fitting in one of the-slots 20 of the block to aline with the tread rib 11' of the block is 4a rail 37 and alining with said rail is a` rail 38 fitting in the slot 30 of the extension of the block. The rails 37 and 38 formaglpartxof the switch track, aH

parallel rail of which is indicated at 39. Extending through the tongue 21,V through the rails 34 and 37, and through the adjacent end of the block", are ybolts 40` securing said rails to the block. Extending through l0' 41 andy 42 rigidly *connecting these latter rails' with the block. As suggested in Fignre 4,1 the slots 20, 26 and 30, are formed to snugly accommodate the ends lof the rails `engaging therein while the' endv faces of the rails abut Hat against the .end walls of said slots. At the same time, 'the treads` of the rails and 38 are snugly accommodated in the seats 28 and 32 while the base flanges of vthese rails as well as the base flanges of the ra-il`sw34 and 37 snugly fit in the seats 23, 29 and 33,.VH Tightjointsgbetween the ends of the rails andthe blockare thus provided.

. Having Ethusv V'described the -invention, what is claimed as newisI A railway frog includingablock having intersectingy flangewafysand Aprovided at one end between saidiangeways with an. upstanding rogpoi'n't and at its opposite end betweenthefflangeways with an upsta'nding double-ended ffrog point.

2. A railway frog including a4 block having intersecting flangewyays and provided at one end between said tlangeways with an upsta'ndingI frog point and. at its opposite betweenlthe iangeways with an upsta'nding ,double-ended rog'point, the latter endy of the block beingformed Aat opposite sides of said double-ended 'frog point with slots to accommodate-the ends of rails.

A railway frog including a block liaving` intersecting flangewaysand provided at one endy between said flangeways with an upstanding frog point and at its opposite end between the" fian'ge'w'ays with an `upstanding"double-ended frogl point, the latter end of the blockbeing formed at opposite sides of said double-ended 4vfrog point 4with slots to accommodatey the ends of rails and the former end of the block being formed with a like slot arranged in alinernent with said first mentioned' frog point.

4. A railway frog including a block having intersecting angeways and provided at one end betweensaid flangeways with an upstanding frog point and at its opposite end between the flangeways with an upstanding double-ended frog point, the" block being provided at the former end thereof with an extension formed to accommodate rail ends lying at opposite sides of the eX- tension and being provided in alinement with one side of said extension with a! slot to receive one of said rail ends.

5. A railway frog including a block having intersecting i-angeways and provided at one end between said angeways with an u'pstanding frog point and at its opposite end between the iangeways with an vupstanding double-ended frog point, the block being provided at the former end thereof with an extension having a slot to accommodate a rail end and .the block being formed at one side of said extension with a like slot to accommodateV a second rail end extending in alineinent with said rst mentioned frog point.

6. A railway frog including a block having intersecting angeways and provided at its ends between the iangeways with upstanding frog points, the block being formed at one end with a slot opening through the bottoni face of. the block and ,exten-ding in alinement with one of said frog points and said frog pointbeing provided with a tail rib flanking said slot and coacting with the outer end edge of said frog point to detine an angular rail tread seat.

7. A railway frog including a block having intersecting flangeways Vand provided at its ends between the liangeways with up-I standing frog points, the block being formed at one end with an extension and the block aswell as said extension being provided with tongues to overlieyrail ends secured to said extension and the block.

In testimony whereof I aiix my signa-- ture.
